Yes. If they've been exposed, assume they are (at best) asymptomatic carriers. Because of the way MG transmits, by the time you've found a sick bird and confirmed a likely MG diagnosis, everyone that "shares space" with them is likely infected - and will be for life.Thank you for this resource I haven’t been on this site yet. I also appreciate the advice in your reply and totally understand there are different approaches to this depending on people’s life and needs.
If I may ask one follow up, it would be safe to assume my other four gals have MG even though there are no symptoms right? I mean they shared a coop so I see no way they aren’t exposed and therefore want to re-introduce the 2 sick ones to the coop once their symptoms subside. (All this assuming their results come back positive tomorrow)
